classmethod connect(serial_number)

Connect to the Thorlabs KST Stage

Parameters:

serial_number (str) – Serial number of the stage.

Returns:

Thorlabs KST Stage controller

Return type:

kst_controller

get_abs_position(axis, axis_abs)

Ensure the requested position is within axis bounds and return it.

Parameters:

• axis (str) – An axis: x, y, z, f, theta

• axis_abs (float) – Absolute position value

Returns:

Position to move the stage to for this axis.

Return type:

float

classmethod get_connect_params()

Register the parameters required to connect to the stage.

Returns:

List of parameters required to connect to the stage.

Return type:

list

get_position_dict()

Return a dictionary with the saved stage positions.

Returns:

Dictionary of stage positions.

Return type:

dict

move_absolute(move_dictionary, wait_until_done=False)

Move stage along a single axis.

Parameters:

• move_dictionary (dict) – A dictionary of values required for movement. Includes ‘x_abs’, etc. for one or more axes. Expects values in micrometers, except for theta, which is in degrees.

• wait_until_done (bool) – Block until stage has moved to its new spot.

Returns:

success – Was the move successful?

Return type:

bool

move_axis_absolute(axes, abs_pos, wait_until_done=False)

Implement movement.

Parameters:

• axes (str) – An axis. For example, ‘x’, ‘y’, ‘z’, ‘f’, ‘theta’.

• abs_pos (float) – Absolute position value

• wait_until_done (bool) – Block until stage has moved to its new spot.

Returns:

Was the move successful?

Return type:

bool

move_to_position(position, wait_until_done=False)

Perform a move to position

Parameters:

• position (float) – Stage position in mm.

• wait_until_done (bool) – Block until stage has moved to its new spot.

Returns:

success – Was the move successful?

Return type:

bool

report_position()

Report the position of the stage.

Reports the position of the stage for all axes, and creates the hardware position dictionary.

Returns:

position_dict – Dictionary containing the current position of the stage.

Return type:

dict

run_homing()

Run homing sequence.

stop()

Stop all stage channels move

verify_abs_position(move_dictionary, is_strict=False)

Ensure the requested moving positions are within axes bounds

Parameters:

• move_dictionary (dict) – A dictionary of values required for movement. Includes ‘x_abs’, ‘y_abs’, etc. for one or more axes. Expect values in micrometers, except for theta, which is in degrees.

• is_strict (bool, optional) – If True, return an empty dict if any axis is out of bounds.

Returns:

a verified moving dict {axis: abs_position}

Return type:

dict
